manager or database administrator.
People who eat a diet slightly higher in protein
tend to have a lower risk of stroke, according to
a new study.
Scientists came to the conclusion after analysing
the results of several large trials that included more
than 250,000 people. However, the findings show
an association, not a cause-and-effect relationship.
The researchers said they can't say whether a high-
er-protein diet may actually lower the risk of stroke,
or whether some other underlying factor is tied to
Scientists disagree about what proportions of
macronutrients---carbs, proteins and fats---in the
diet may lead to optimal health. Some researchers
argue that carb-heavy diets are responsible for
surging rates of diabetes and obesity, while other
studies suggest that high-protein diets raise the
risk of cancer as much as smoking. And several
lines of research point to fat-rich diets as a culprit
in heart disease and stroke.
To evaluate the role of protein in stroke risk, Dr
Xinfeng Liu, a neurologist at the Jinling Hospital
in China, and colleagues looked at the published
studies on stroke and protein consumption, and
found seven that specifically looked at the risk of
stroke. These studies were prospective, meaning
that researchers started out by asking people about
their dietary habits, and then followed them for a
number of years and counted how many of the
study participants had a stroke.
Across the seven studies, higher levels of protein
were associated with a lower risk of stroke. The
study also showed a dose-dependent response,
meaning that the more protein people ate, the lower
their risk of stroke. For every 20 grams of protein
people ate per day, there was a 26 per cent lower
risk of stroke.
It's not clear how protein consumption might
influence stroke risk. But "studies have shown that
dietary protein may reduce stroke risk via its
favourable effects on blood pressure. In addition
to lowering blood pressure, the protein diet also
significantly lowered triglycerides, total cholesterol,
and non-HDL cholesterol," Liu told Live Science
in an e-mail.
Not all proteins were created equal, however.
High fish consumption was linked with the lowest
risk of stroke in the study, and past studies have
tied high red-meat consumption to greater stroke
risk, Liu said.
Diets high in vegetable protein seemed to be less
protective against stroke than those that included
a lot of animal protein. However, people in the
studies who ate lots of animal-based proteins ate
significantly more protein than those on a plant-
based diet, which may have made it more difficult
to detect the trend, the authors wrote in the paper.
In addition, it may not be the protein itself, but
other elements that typically go along with a high-

protein diet, that lead to the benefit.
"Dietary protein intake tends to be associated
with other nutrients that may prevent stroke, such
as potassium, magnesium and dietary fibre," the
